The STM32 Elevators Monitor System is a state-of-the-art project showcasing the powerful capabilities of the STM32 microcontroller for real-time elevator control. Leveraging the robust features of C, this project demonstrates intricate USB UART communication, precise timer management, and advanced data structures for efficient data handling.
- Microcontroller Clock: Configured with a pre-scaler to operate at 32 MHz, allowing for 16-bit timers with a count of 35999 to achieve 1 ms time steps, further scaled internally using
TIME_STEP. - Communication: Implements USB UART communication for reliable data transfer, ensuring seamless interaction with the Qt application.
- Timers: Utilizes advanced timer configurations to manage elevator states and transitions with millisecond accuracy.
- Data Structures: Employs carefully designed data structures and leverages
__weakmethods for data deserialization to facilitate maintainability and scalability. - CRC Validation: Incorporates CRC-8 checksum for enhanced data integrity, ensuring the reliability of the communication protocol.
- Hardware Configuration: Pins are activated according to the STM32 datasheet to support a 48 MHz UART operation. The system is based on CubeIDE version 1.8.0 and is configured for crystal oscillator with a rising edge.
The design is inherently scalable, allowing for the addition of more elevators. It supports a variety of features such as ADCs and DMAs, providing a flexible base for further development.
